The object of the experiments described in this report was to develop the use of Oregon material to produce a low-cost flux for commercial ceramic use. The materials tested include volcanic ash, pumice, and, a material new to the ceramic field as a flux, perlite. These materials were combined with...
Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...
